what processes in your cells produce the co2 that you exhale?
Answer:
Co2 is released from the pyruvate that is formed during glycolysis, and CO2 is also released during the citric acid cycle.
Explanation:
Cellular respiration in mitochondria produces [tex]CO_2[/tex] as a waste product, exhaled during breathing.
Cellular respiration occurs mostly in mitochondria. During cellular respiration, glucose and other nutrients are broken down to make ATP. This procedure produces [tex]CO_2[/tex]. [tex]CO_2[/tex] from mitochondria diffuses into the circulation.
Breathing exchanges [tex]CO_2[/tex] for oxygen in the lungs from the circulation. Your body releases [tex]CO_2[/tex] when you exhale. This important cycle eliminates unwanted [tex]CO_2[/tex] and supplies cells with oxygen for respiration and energy generation.

Which of the following correctly describes the two phases of the cell cycle?
A. Cells grow and develop during interphase. Cells reproduce during the mitotic phase.
B. Cells grow and develop during the mitotic phase. Cells reproduce during the interphase.
C. The nucleus of a cell divides during interphase. The cytoplasm of a cell divides during mitotic phase.
D. The nucleus of a cell divides during mitotic phase. The cytoplasm of a cell divides during interphase.
Answer: the answer is A
Explanation:
Cell cycle refers to the series of processes that leads to the growth/development and division of a cell. The cell cycle uses MITOSIS for cell growth. Mitosis comprises of two distinct stages namely: INTERPHASE AND MITOTIC PHASE. The interphase is referred to as the resting phase of the cell in which the cell grows and develops.
On the other hand, MITOTIC PHASE is the stage where the actual division of the nucleus (karyokinesis) and cytoplasm (cytokinesis) generally called CELL DIVISION occurs. Therefore, the cell reproduces i.e. one cell forming two, in the mitotic phase.

What can you infer is the reason fruit flies are the most commonly used organism for this type of investigation
In the case of genetic investigation, scientists used fruit flies as their model organism since they share 75% of the genes that cause disease with humans. Fruit flies are also great to work in a research setting because they are relatively easy to take care of, especially compared to larger and more expensive organisms like rats or fish.Answer:

Answer:
it's option d) It gives the body a spherical shape.
The effect of hydrostatic equilibrium on a solar system body is that It gives the body a spherical shape.
What is hydrostatic equilibrium?Hydrostatic equilibrium describes liquid or fluid at rest.
A body of solar system such as Earth has a spherical shape which is not perfect. This spherical shape of Earth and other bodies of the solar system such as;
Mars, Venus, Jupiter, Uranus etc are caused by the hydrostatic equilibrium.Thus, we can conclude that, the effect of hydrostatic equilibrium on a solar system body is that It gives the body a spherical shape.

In __________ ribosomes can attach to the mRNA and begin translation even though transcription has not been completed.
Answer:
prokaryotes
Explanation:
All cells translate using ribosomes. Prokaryotic DNA lacks a nucleus, therefore translation happens before transcription. Simultaneous transcription and translation takes place.
What is translation in prokaryotes?In all cells, translation takes place at ribosomes. Prokaryotes translate DNA before transcription is finished because their DNA is not bound by a nucleus. Both transcription and translation take place at once. When a start codon on mRNA attached to a small ribosomal subunit is recognized by an initiator tRNA anticodon, translation can start. A second tRNA is recruited as the big ribosomal subunit joins the tiny subunit.
This is not conceivable in eukaryotes because translation takes place in the cytoplasm outside of the nucleus, whilst transcription takes place in a membrane-bound nucleus.
